On several of mine, I backed the screws out until they were barely adding any tension at all, and the holsters were still firmly holding the weapons. A gave them a dab of blue screw glue, and they are holding up just fine.
If you want some additional retention, the same company also makes almost the exact same holster with a synthetic thumbbreak strap added. I bought one of those on a clearance sale last year, and have used it both with and without the strap installed, with no problems.
Should mention, all my units are for Glocks.
